To all ZLYZOYH; it may concern:

Be it known that I, Josnrn: S. .MAYER, a citizen of the United States, residing at; Trenton, in the county of Mercer and State of New Jersey, have invented 2r new and useful Improvement, in Pottery-Kilns, of which the fol lowing is u specification.

My invention relates to apparatus for the fusion of porters glaze. Its object is to furnish n simple and inexpensive means of fusing glaze forpotters use.

16 consists in :1- novel (iOllllJlllfilElOllOf one or more fret-kilns with n potters kiln.

l accomplish the object of my invention by means of the device illustrated in the accompanying drawings, wherein Figure 1 is o plan showing a section of n pottcrs kiln (contained between two ofit-s fires) embodying in improvement. Fig. 2 is an elevation of the some, looking from the inside of the kiln. Fig. 3 is a transverse vertical section taken on the line [C y.

Siinilarlciters refer to similar ports through out, the sever-cl views.

A is the oven or interior chmnberol' the kiln in which were is burned.

(a (2" are two of the fires which generate the heat for oven A.

7; is an annular flue inching n circuit of the kiln beneath the floor, into which all the fires discharge their heel.

if ii are lines mode in the wall of l; iln.through which the iii-cs c a discharge their hen-l; into the annular line b.

b is a radial fine connecting the due h with center iluc,o, through which the heatis transmitted to the center of the oven.

b* If are two bugs or fines built; against the inside of lcilnwnll, in open communication with fine 1), and through which the heat is discharged into the oven near its periphery.

G is u fret-kiln for the fusion of glaze, preferably constructed in sections, the bot-tom (3 being composed of one piece of burned firecluy, and fitted with a continuous groove extending around it near the outer edges there ofiinto which the projecting tongues on the two sides and two ends snugly fit. The two end pieces are fitted close to bags 2) b and grooved on their inner surfaces to receive the projecting tongues on ihesides and bind these sides together the end nieces being kept firmly in position by being jammed in between bags 22* b 3 is a plank of burned fire-clay, bridging the space between bags b" Its center is supported by Wnllf, bnillsnpon the top of the innor side of fret-kiln O. The suggers of were are piled on plank y and carried up to the regular height, reducing the displacement in kiln caused by the fret-kiln to three suggers only.

G C are lines through which the bags 5* b discharge a portion of their heat into fret,- kiln G.

6" G are two openings in fret-kiln G, establishing a. free union with the general heat of oven A.

e is thcchnrgiug-door in kilnwall udhrough which the product to be fused is passed into the reservoir of fret-kiln C.

e is the tapping-hole extending through the lcilnwrnll in into the bottom purl; of frcukiln 0. It is used to draw oil the liquid glaze while in e stole of fusion.

11 is a basin walled in the brick-work ofhiln between fires c c. It is used in connection with e. hydrant to supply it with water, and a wastepipe, 2 at; its bottom part; to draw water off. It; is partly filled with water, and the liquid glaze discharged into it through the lapping-hole c, which, upon contact with the woteigiiies into myrinds of infinitesimal particlcs, rcsulting in a powder too line to need the pounding process.

The ireb-l iln,ufter being lined with silicajs charged through the door c. The heobfrorn the fires a u is discharged through lines I) 1) into the main annular flue Z), and is distributed through fine Z) and bags I) b 'E-OlllG center and periphery oi" ovcn,respectivcl .n The heat passes from hugs b If, through dues G O into fret-- kiln (l, and, in conjunction with the free heel; of the oven received through fines G" Cflfuses the glaze therein. The liquid glaze, when properly fused, is let out through the tappingliole 6' into the basin d,partly filled with water, with the result previously described. The kiln is again charged and the operation repent-ed.

What I claim as new is- V lhe combination and arrangement of potiers kiln AJret-kiln (3, bags E 6 and fines O, G", C" and C substantially as specified.
